Pulling GT911 touch interrupt pin down with a resistor with ESP32 S3 controller
Posted: Sun Oct 27, 2024 9:12 am
Hello,
I have this RGB 7" display I purchased from aliexpress, it runs ESP32-S3 and I believe ST7262 RGB display driver.
The problem is in the initialization of the GT911 touch driver.
If the interrupt pin is configured as input, it goes to HIGH all the time and then the GT911 is locked into interrupt mode.
I can't configure the pin to be input and pull it down at the same time.
My idea, according to the schematic. Which all the pins are pulled-high !! I don't know why they pulled the interrupt pin to HIGH as it will lock the code and the ESP32 can't process any code.
